Binding Lock Cylinders
Binding or sticking door lock cylinders and keys that are hard to insert or remove may be corrected in many cases by applying the proper lubrication.
The recommended materials for lubricating these components are (in order of preference):
^
Lubricant GM P/N 12345120, or equivalent.
^
5 W-30 synthetic motor oil.
^
Silicone spray GM P/N 1052276, or equivalent.
Penetrating lubricants such as GM P/N 1052949 and WD-40(R) ARE NOT RECOMMENDED because they wash out the original lubrication and
eventually evaporate, leaving little or no lubricating material. However, if these materials are used to unfreeze or loosen lock cylinder components. Refer
to Steps 2 through 4 below for proper methods of lubrication.
